It was a special deal signed in 1994, that covers personal and their families at that particular installation. Considering the clandestine nature of the work being conducted it was a security measure put in place by the American Government just in case.Got any more details on that immunity agreement?
One wonders whether it is legislation, or a gentlemans agreement. Then one wonders how far the agreement actually extends to cover family. If it is just a nod and a wink agreement between a couple of spymasters and nothing is enshrined in legislation then she could technically be required to appear before a court.
It get's muddier and muddier.
